目的 探讨笑气吸入和硬膜外麻醉减轻或消除产痛及对产程、胎儿、分娩方式的影响。方法 将190例产妇分为三组 ,笑气吸入镇痛 (笑气组 )、硬膜外麻醉镇痛 (硬膜外组 )与未给镇痛 (对照组 )。观察比较三组的产痛程度、产程时间、分娩方式、新生儿Apgar评分 ,产时出血量和产后出血率。结果 两种分娩镇痛都有效 ,笑气吸入分娩镇痛可缩短产程 (P <0 0 1) ,硬膜外麻分娩镇痛有产程延长且增加阴道分娩的助产率 (P <0 0 1)。结论 笑气吸入分娩镇痛效果好、简单 ,产妇乐于接受 ,对母儿无不良影响 ,有应用价值。
Objective To investigate the effects of inhalation of noxious air and epidural anesthesia on the reduction or elimination of labor pain, labor, fetus and mode of delivery. Methods 190 pregnant women were divided into three groups: nausea (inhaling nitrous oxide gas), epidural analgesia (epidural) and no analgesia (control group). The levels of labor pain, labor duration, delivery mode, neonatal Apgar score, intrapartum hemorrhage and postpartum hemorrhage were observed and compared. Results Both labor analgesia was effective, labor gastrulation and labor analgesia could shorten the labor process (P <0.01), prolonged labor delay and labor-saving rate of vaginal delivery during epidural anesthesia (P <0.01 ). Conclusion Numbness inhalation labor analgesic effect is good, simple, maternal willing to accept, no adverse effects on the mother and child, have application value.
